**Title Credits**: Gentle reference to the homonymous [talk](https://pyvideo.org/europython-2013/never-get-in-a-battle-of-bits-without-ammunition.html) presented at 
**EuroPython 2013** in Florence by my friend **riko** (_a.k.a._ Enrico Franchi ).

## Abstract

The `numpy` package takes a central role in Python scientific ecosystem. 
This is mainly because `numpy` code has been designed with
high performance in mind. 

This tutorial will provide materials for the most essential concepts
to become confident with `numpy` and `ndarray` in (a matter of) `90 mins`.

# Outline

- Introduction to NumPy Arrays
    - numpy internals schematics
    - Reshaping and Resizing
- Numerical Data Types
    - Record Array
    
    
**11:30 - 12:00** (_30 mins_) Indexing and Slicing
    
- Indexing numpy arrays
    - fancy indexing
    - memory management
    - broadcasting
    
- Slicing & Stacking
- Vectorization

**12:00 - 12:20** (_20 mins_) Bits of Data Science with NumPy

- Serialisation & I/O
    - `.mat` files
- Array and Matrix
    - Matlab compatibility
- Memmap 
- Beyond Numpy

### Python version

The minimum recommended version of Python to use for this tutorial is **Python 3.5**, although 
Python 2.7 should be fine, as well as previous versions of Python 3. 

Py3.5+ is recommended due to a reference to the `@` operator in the linear algebra notebook.
